Problem ReCreating Access report in Crystal Reports

I'm trying to recreate an access report as a crystal report and I'm having trouble.

Basically, the Access report runs a stored procedure (which returns nothing, but populates tables), then those tables are queried to display the data on the report.

So I'm trying to figure out how to run the procedure with parameters from a crystal report. I've got the second part fine, if I run the procedure manually, then display the report I get the appropriate data.

How can I execute the stored procedure before querying those tables from Crystal Reports???
